11 Claims.

My invention relates to cleaning attachment for integral casting type machinesand particularly to mechanism for cleaning the knives by which the type slugs are trimmed to a predetermined thickness when ejected from the mould disk.

The invention relates more particularly to Linotype and Intertype machines. The final action of these machines is to trim the cast line (type slug) to a predetermined thickness by forcing it between perpendicular, parallel knives located in the rst elevator and then depositing it into a line reservoir. This nal operation leaves the trimming of excess metal adhering to the useful edges of the knives, the removal of which is the concern of this invention.

Because the trimming knives are canted" eighth of an inch (1 motion and to ease canting causes the perpendicular partially efficient.

Therefore, when one- 30) in live to lend a slicing the burden of ejection, the a mechanical difculty, so that swipe of the ag can be only adhere forceably to the type face of the slug and in print appear as tiny blots or blur the surrounding letters, which is an trade as a dirty face.

Examples of dirty face the type has supplementary hand cleaning by the pared for long press runs of books,

While wipers are usually provided for removing such fragments from the trimming knives the case of a hot slug, the wiper cannot move up and down over the knife edges and the wiper fails to operate without giving any indication of the trouble to the operator.

In accordance with my inventionV these diffiand a simple, inexpensive wiper provided which functions to remove chips and fragments from the trimming knives very effectively. Moreover in a preferred form of my invention hereinafter described the wiper is actuated by a, manually controlled element of the mechanism such as the assembly elevator so that in the event the mechanism functions improperly due to a hot slug or for any other reason, the operator is immediately advised of the condition and can remedy the same so as to avoid further operation of the mechanism in an improper manner.

One of the objects of my invention is to provide a novel and inexpensive wiper construction for removing type metal from the edges of the trimming knives of integral line casting type machines.

Another object of my invention is to provide manually operated means serving to indicate improper operation of the mechanism.

A further object of my invention is to provide a wiper for the knife blades actuated by the assembly elevator.

'I'hese and other objects and features of my invention will appear from the following description thereof in which reference is made to the accompanying figures of the drawing which ilplied to Linotype In the drawings:

Fig. 14 is a similar view of the device as applied to a machine formed to receive the same, certain parts of the device being broken away.

In that form of my invention chosen for purposes of illustration in Figs. 1 to 5, 1, 8, l2 and 13 of the drawings I have illustrated a wiper in the form of an attachment to be applied to existing Linotype machines wherein there is a bracket l5 or other suitable means secured to the lower4 portion of the assembly elevator 39 by means of a set screw 38. An arm 24 extends from the bracket on the assembly elevator toward the mold disk and trimming knife and is adjustably supported on a projection 35 of the bracket by means of the slot 3B and screw 31 on one end of the arm 24. Adjustment of the arm 24 by the set screw 38 or by the screw and slot 36 and 31 renders it possible to adjust position of the arm and the tension of the wiper blades against the knives. Thus it is possible to urge the wiper toward the knife blades with a variable force depending upon the position of the arm In this way I insure contact of the wiper with the knife edges throughout their length despite the fact that the knives are usually located in an inclined position.

A wiper IE designed to cooperate with both of the knives 2| an-d 26 is carried by the arm 24. The wiper is secured to the arm by suitable screws or the like to permit removal or replacement thereof and is located closely adjacent to or in contact with the knife edges to remove fragments of metal therefrom. As illustrated the wiper IB may if desired have a lug 4E carried thereby and positioned to engage the fixed knife at a point spaced from its cutting edge so as to hold the wiper from direct contact with the knife edges as the wiper moves up and down thereby prolonging their usefulness.

In the construction of Fig. 1 a single wiper serves to remove material from the edges of both knives. However, it may be desirable in some instances to employ a separate wiper for each knife edge. In the construction of Figs. 3 to 12 I have illustrated constructions wherein tw-o separate wiper blades are provided. Although two separate arms or supports for the separate wipers may be used I prefer, as shown, to support both wipers by the same arm 24. Since one of the `bla-des is adjustable for the purpose of trimming the slugs to different thicknesses it is desirable when using two wiper blades to have the blade associated with the movable knife adjustable with the knife. To this end I have shown the wiper I8 of Figs. 3 and '1 as secured to a block 20 formed with a recess engaging a projecting member on the movable knife. The projecting member may conveniently be formed on a strap 22 secured to the knifel by overhanging ends engaging the knife adjusting bolts 25 and knife retaining bolts 21, as shown in Figs. '1, 8 and l2. The construction shown in these figures of the drawings illustrates the invention as applied to a"Linotype' machine having a movable knife of the type shown in Fig. 5.

When this type of construction, that is one embodying two wipers, is used on an Intertype machine having a trimming knife of the type shown in Fig. 6 the device may have the form illustrated in Figs. 9, 10 and 1l, wherein the wiper 28 cooperates with the stationary knife 26 and the wiper 39 cooperates with the movable knife 34. The wiper support for the wiper 30 is formed with a portion 3| extending into the longitudinal trough of the knife and with a portion 32 engaging the rear of the knife block 34 as shown in Fig. `l0.

In the Intertype machine the movable blade is adjusted by means of a knife setting device 1ocated between the knife and the assembly elevator. For this reason the arm 24 by which the wipers are-carried in such constructions is offset as shown at the left hand side of Fig. 10 so as to extend around the knife setting mechanism and between the same and the adjacent edge of the mold disk.

In each of the forms of the wiper construction shown in Figs. 3, 4, 9 and 11, the wiper extends lengthwise of the slot between the knife edges so as to bring the wiper into engagement with the entire length of the knife edges even when the length of movement of the wiper is less than the length of the mold slot or knives.

In the operation of the mechanism described the operator actuates the assembly elevator at the end of every line to raise the matrices into position to be moved over to the first elevator. The movement ofthe assembly elevator is effected manually and involves vertical movement of the elevator in a line substantially parallel to the knife edges although spaced therefrom. The arm 24 and wipers are thus moved up and down at each operation of the assembly elevator and with each transfer of a line of matrices to the first elevator for the formation of a slug.

The mold disk wheel of a line casting type machine when at rest, on its lock-up studs or while revolving is at no time closer than La inch to the useful edges of the trimming knives, and as the wiper plates are less than e inch in thickness, the invention is at all times effective and meets an obstruction only when the ejector blade is performing its normal function of ejection or upon the occurance of a hot slug.

If a hot slugv is formed and the space between the mold slot and knives is obstructed with the assembly elevator either above or below the slug or the ejector blade, the assembly elevator will not be permitted to operate in the proper manner and the operator will immediately be notified of the trouble. In this Way manual operation of the wiper mechanism through the assembly elevator serves as a trouble indicator as well as a simple and effective wiping device. An additional advantage of the device is that it allows the space and fastening points now taken by the old wiping systems to be used for other purposes if necessary, and .eliminates a number of the moving partsof the machine.

While I have indicated that the mechanism may be applied to existing machines as anattachment, as shown in Fig. 14 it may be embodied in new machines by the use of an integral projection or other means 35 for supporting the arm 24. However, I prefer to construct the arm24 so as to be adjustable with respect to the assembly elevator by somesuch means as the slot 36andscrew 31 to permit variation in the force with which the wiper blades engage the knives.

The forms of my invention herein shown and described are designed for use on Linotype and Intertype machines but it may be desirable to make numerous changes and modications in the form and arrangement of the parts to adopt the same for use on other machines or to facilitate or reduce the cost of manufacturing or assembling operations. It should therefore be understood that those embodiments of my invention herein shown and described are intended to illustrate my invention and are not intended to limit the scope thereof.
